GRAND RAPIDS (WZZM)- This morning's rain will help green up lawns and trees. But lightning also helps plants grow. That is because lightning releases free nitrogen in the air. A heavy does of nitrogen gives plants a nutritional boost.

WZZM 13's Greenthumb Rick Vuyst explains, "After a wild lightning storm, you can smell that ammonia like smell in the air. Ammonia is available to plants as greening power. It super charges the air, and then super charges our landscape the next day when everything looks green."
